Worst part? They never tell you when they lose interest. One day, you wake up & realize they're pulling away. Fewer chat? Then suddenly, you're not a priority anymore. They'll say that they've been busy. They'll apologize for not getting back but the apology will feel empty.
There's a reason airbenders were raised as monks and peacekeepers. Their power is so dangerous that it had to be restrained by discipline.
If airbenders ever fought without holding back, the Avatar world would look very different.
